Bach: Brandenburg Concerto No.4, 1st mvt. The first (and closing) ritornello (b.1-83 & 345-427) Melodic Structure The opening ritornello of a late baroque concerto grosso such as this contains all of the melodic material for the rest of the movement. Bach’s melodic lines are constructed from a number of small cells – short patterns of notes with a distinctive profile. Identify the basic melodic shapes on the first page of the score:- Bar Instrument(s) Characteristics 1 Fl 2 Rising and falling arpeggio in even semiquavers Bar Identify any new cells between b.20 and 83 Instrument(s) Fill in the following table:Bars 1-6 7-12 13-22 23-34 35-42 43-56 57-62 63-68 69-78 79-83 Cell(s) Characteristics HWK: Comment on the ways in which Bach builds his first ritornello from a few melodic cells. Cells A F2 B/Bi F1/2 triad as semiquaver arpeggio, up and down three notes by step, down then up; straight quavers (B) or 2 semiquavers and a quaver (Bi) V/F2 b13 semiquaver scale, rising V/rpV b14 descending arpeggio in semiquavers, with repeated notes F1/2 b35-8 longer melodic cell built from elements of B and C C D E b1 b3-4 Uses of the cells Cells A and B together are used to punctuate the ritornello, bringing the music back to its first idea, e.g in bars 23-35 and 57-68 Cell B forms part of E and is the building block for the flute parts in bars 44—6 and 69-74 Cell C forms part of cell E (b.38 – descending) and is an integral element in the passage between bars 47 and52 Cell D takes on a life of its own and is used at all levels of the music, including the bass to form chains of descending arpeggios, e.g. bars 53-57 Cell E is really a composite of other elements, but has an identifiable role in the middle of the ritornello between bars 35 and 44, when it is linked to a version of cell Bi (see above)
